These engineering tools allows designer to:
Design of individual components of the product
Static and dynamic analysis
Virtual simulation and report completion of its functionality
Creation of technical documentation for technology
In our case, we chose a suspension arm for the stress analysis and analysis of the technology.

TECHNOLOGICAL SOLUTIONS
After that the designer creates drawings, process engineer begins with designing of the manufacturing process for
individual components and their subsequent assembly into a complete assembly. The manufacturing process means:
Choosing of working machines and tools for the production of individual components
Determination of working conditions
Generation of CNC programs (if there are used CNC machines in the production)
We can use of technological modules which are parts of the CAD systems (CATIA and NX). These modules allow
engineers to virtually simulate a manufacturing process. Technologist can choose:
Method of machining
Cutting machining conditions
The control system of CNC machine
Analyze a precision after machining
On Fig.3 you can see a design of injection head for production suspension. There is example of machining of the main
board of the injection head. When control system is defined (in our case SINUMERINK) technologist can simulate a
progress of machining. It can simulate only a cutting tool or whole machine. The biggest advantage of this
technological module (in case of NX) is that we can simulate that the machine runs directly according to the CNC
program. In many other technological tools, the simulation is run only by the CL data, which are not gone through the
post-processor.
